A French architect has a vision for a sustainable floating city that looks like a manta ray

Jacques Rougerie says he has a special affinity for the sea, which makes sense—his life’s work has been designing aquatic architecture. Rougerie’s SeaOrbiter ship, a fantastical roving laboratory that has been described as “a starship Enterprise for the water,” is currently under construction. And his next design, for a floating city where up to 7,000 ocean-loving humans can live, is an even more extreme demonstration of his passion for the underwater world.
